Because PVC and CPVC pipe and fittings are designed to convey liquids, most companies recommend testing with water. The purpose of the test is to locate any leaks at the joints and correct these prior to putting the system into operation.
Pressure test shall be a hydrostatic leak test, only where a hydrostatic leak test is impractical, pneumatic leak test may be substitute but it shall be subject to Owners prior approval. Lines and systems which are open to the atmosphere, such as drains, vents and open safety valve discharges, do not require pressure testing.Pressure Test Procedures - Stanford UniversityMechanic Pressurizes the system, raising the pressure in the system gradually until the designated test pressure is achieved : 13. Mechanic . Maintains this test pressure for 10 minutes before inspection. Then, if test is above maximum allowable working pressure (MAWP), reduces to MAWP while making a full thorough inspection for leaks. 14.Optimized Fire Protection in Tank Farm - Fire Safety SearchOptimized fire protection in tank farm Alternative concept offers same level of safety.
